SPECIFICATION forming part of Letters Patent No. 739,334,dated September- 22 1903. I

Application filed May 13, 1903- Serial No. 156,864. CNo model-3' To all whom it may concern."

Be it known that I, STEWART: H. MOORE, acitizen of the UnitedStates, residing at Ohicago, in the county of Cook and State of Illinois, have invented a certain newand useful Improvement in Valves, of which the following is a specification.

My invention relates to an improved article of man ufacture adapted to be used for valves, valve-disks, and the like, and has for its object to provide a new and improved device of this description. I

My invention is illustrated in the accompanying drawings, wherein- Figure 1 is a view of a pump with parts broken away, showing my improved valvein position. Fig. 2 is a view of one of the valves. Fig. 3 is an enlarged section therethrough. Fig. 4 is a view showing one way of combining the pieces of the outer covering for the valve. Fig. 5 is a View showing a modified method of connecting the parts of the cover in g. Fig. 6 is a view of the valve-disk embodying my invention.

Like letters refer to like parts throughout the several figures.

' In the use of valves in pumps and the like, for example, it is desirable to have a Valve which will be durable and which will adapt itself to the seat in connection with "which it is used and which will also remain unafiect ed by the fluid or material passing through the pump, and this is particularly true when this fluid is hot or is some. other fluid than water.

Referring now to the drawings,l have shown a Valve A in Figs. 1, 2, and 3 adapted to be used in pumps for pumping any desired material. This valve consists of an inner elastic part A, which may be rubber or any other suitable elastic substance. This elastic inner portion is covered by a light homogeneous parts of the covering are placed about the inner elastic portion and are held in position in any desired manner, as bybrazing together. This method completely incases the elastic material and seals it within the covering, so that it is protected from the fluid with which tion of the lapping over of the parts A is illustrated on an enlarged scale in Fig. 4. It is of course evident that the parts of the covering of the device may be connected together in any desired manner, and I do not limitmyself to such connection. I have shown, for example, in Fig. 5 a different connection where the edges of the parts of the covering are lapped overand the joint thus made, and this joint may be soldered or brazed or otherwise treated. In Fig. 6 I have shown a valve-disk constructed in the same manner and adapted to be used wherever applicable. With this construction it will be seen that adevice is produced which is elastic and which yet has the characteristics of a metal valve and that when this valve is used it accommodates or adapts itself to the seat or surface in connection with which it is used, because of the yieldingsurface of the device itself, and that it thus produces a tight joint. This device is also noiseless when used in pumps as a valve, for example, or as an elastic liner between heavy bearings and does away with hammering, jar, and the like. This valve may'also be used in pumps, for example, that are used to pump hot liquids or acids or corroding gases or oil or any other material which hasa tend-' .enoy to attack the valve and when so used is free from attack and has the beneficial qualities hereinbefore described.

I'have described in detail a particular construction embodying my invention; but it is of course evident that this construction may be varied and changed as to the details with out departing from the spirit of my invention. For example, the manner in which the pieces of the covering are connected together may be varied, and the number of piecesinto which the covering is divided and the par: ticular form or shape may be altered.

When the device ,is used, for example, as a liner for heavy bearings, it will of course take the shape required for this use.

a the device comes into contact. The construc- I have not designated all the uses to which the device may be applied, as such uses will readily occur to those versed in the art.

I claim V 1. A valve consisting of an inner elastic portion with an outer protecting metallic covering completely inclosing said elastic portion and sealed to protect the elastic portion from the fluid.

2. An article of manufacture comprising an inner elastic portion, an outer sheetmetal covering consisting of parts connected. together at their meeting edges so as to 001m pletely inclose the said elastic material.

3. A valve device consisting of a unitary fiat disk made up of a sheet-metal outer covering and an inner elastic portion confined within said covering and protected thereby.

4. A valve device comprising adisk of elastic material, a sheet-metal covering therefor comprising two or more portions provided with engaging parts fastened together so as to form a unitary construction.

5. An article of manufacture comprising an inner, elastic portion having an opening therethrough, an outer sheet-metal covering consisting of two'parts connected together and provided with laterally projecting parts which extend into said opening and along the outer edge of the elastic portion, said projecting parts meeting and sealed so that the elastic portion is completely inclosed.
